I* Application led February 15,1905. `Berial No. 246,738.

1'0 are whom it may concern:

` Beit known that we, SAMUEL DENTON and Vl'irwann S. "VEEN, citizens ofthe United' States, and .residents of Great Falls, in the county ofCascade andA State of Montana, have invented a new and improved RotaryEX losiv'e-Motcrr, of whichy vthe following is a ful clear, and exactdescription.-

The invention relates to a rotary explosive motor, according to thepreferred embodiment of which a' circular cylinder is connected with arim by means of radial. pockets, the whole constitutin a iiy-wheel, andsaid pockets carrying ra ially-movable 'abutments which coact with a:stationary piston carried `by a stationary shaft, on which the cylinderis mounted to turn, and the shaft and piston being provided with )ortsfor the inlet and exhaust of the motor uid? The invention resides incertain novel features of construction and organization, which will befully set forth hereinafter and pointed out in the claims. f Referenceis tobe had to the accompanying drawings, which illustrate as an examplethe preferred embodiment of our invention,

vin which drawings like characters of refer.

ence indicate like parts in the several views, and i'n which.-

Figui- 1 is a vertical section of the invention, taken across the pistonand the shaft on Aessentially the line 1 l of Fi.' Fig. .2 is asectional view illustrating t piston, taken on the line-2 2 of Fig. 1.Fig. 3 is a longitudinal section taken on the line 3 3 of Fig. 1.

Fig.. 4 is a side elevation of the rotating part of the engine g andFig. 5 is a section on the line 5 5 of Fig; 1,A showing one of theabutment-pockets and the abutment sliding therein.

As shown .best iii-Fig. 3, a frame is provided, which comprises twobearings 10 and two boxes 11 outward of the bearings '10. The boxes 1,1securely carry a shaft 12, which,

las shown in Figs. l and 2, has a flattened enlargement 14 integraltherewith and constitutng the piston of the engine. Turning recly aroundthe shaft 12, at eachside of the enlargement or piston 14, are lhollowtrunnions 15 and 16, these trunnions also turning in the bearings 10.The trunnions 15 and 16 are formed integral with or suitably connectedto the rotating cylinder 17. This cylinder is circular in Iform and maybe constructed in -any manner.l here shown, .it is formed with sidewallsconnected by'tie-rods 18 and clamping between themthe outer orperipheral walls of the'cylinder.l yThe cylin-` der is provided withradially-extending'pockets 19, preferably formed, as shown bestin Figs.ll 'and 5, of parallel side plates integral with the peripheral wallofthe cylinder and end plates integral with'the end walls of the;cylinder and clamped in place by tie-rods 18a. i

.A Weighted rim 20 incloses the cvlinder and abutment-pockets and isattached to the outer end-scf the ocketsto form, with the pockets andwith t e c lindenwhat is essentially the ily-wheel of t e engine.

21 indicates the abutments which slide the abutment-pockets and' areprovided with' 'packing-strips 22 at their inner ends, said strips being adapted to run around the piston, as shown, and edect a tightconnection therewith. The abutments 21 are provided with openin s 23, inwhich are arranged springs 24, t ese springs pressing the abutmentsinward against thexpiston, but yielding to force the abutmentscompletely inter their pockets, as shown with respect to t horizontalabutments in Fig. "1. 25 indicates l` sparking plugs or other ignitindevices, which are' arran ed o ne between eac. pair of abutments anare-operated to ignite theexplosifve mixture, as will be fully set forthhereina ter.

As shown in Fig. 1, the piston 14` is formed by horizontally Wideningthe shaft 12, the

widened or enlarged portion having rounding corners and `being slightlythicker at one side 'than at the other. he shaft 12 is formed at one endwith an inlet-port 26 and at the other end with an exhaust-port 27.These ports` do not communicate with each other, lout-if" they leadintothe piston, and the inlet-port 26 lcommunicates with the other sideof the piston by means of transverse ports 28, While the exhaust port 27communicates with the lower'side of the istonlv by means of transverseports 29. hese parte 28 andv29 extend toward-the thin edge of thepiston, and the thickened edge of the piston is provided with atransfer-port 30, leading from the top of the piston to the bottomthereof and pro-v i vided with a valve 321, which seats againstv thereturn-of fluid from the bottom l piston tothe top. Iitheoperation ofthe engine. assu fthe movement oi the parte continuing, wheny to thelower side of` the devices, ln Fig. 3, 32 indicates a sparking ton. I

:around to thehorizontal, the abutment folton, *'ing the and transversebranches leading Berl] the `parts to be in. theposition shown in Fig.

l and the rotating elements to be moving in the direction of the arrowapplied to the rim i2() in saidyiew, the topiabutment 22, moving letwardfrom the inlet-port 28, will draw into thelcylinde'r a quantity of theexplosive mixture. "ViThen` the top abutment moves lowing will-compressthis mixture and vforce it through the transiter-port 30 into the spaceat the lower lett-hand side of the piston, and,

said .top abutment kas:itunes a position below the piston the. mixturelshould be ignited. At vthe -Feriodoi ignition the compressed mixture'ies at the lower lett-hand side of the piston and an impulse is given tothe rotating parte. The burned gases iare exhausted by the followingpistonl pressing the gases out through thel'ports 29. The mixture there-'lore is drawn into the cylinder at the upper side oi the piston, and asthe parts rotate the mixture is compressed `and forced through iston, itbeing ignited at the loweileft-lliand side and exhausted at thelower:right-hand side. The rotating parte, therefore, receive tour impulses'i'or' each revolution, causing the engine to operate evenly andeiiectually. The spark-plugs, may be operated by any 'desired coil andappurteuancc. and in Figs. 3 and 4, ,33 indicates contact eri z inconnection with the spark-'plug and operating with a contact 34 on theframe or" the engine, the arrangement being such as to cause the sparkto pass at each plug when the folug reaches a position 'below theleft-hand side of the pio- 'Various changes in the-form, proportions,and minor details of our invention may be resorted to at will withoutdeparting trom the spirit and scope thereof. Hence We consider ourselvesentitled to all such variations as may lie within the terms of ourclaims.
